Question

3 (x-9)+(-6x+14)=-5

5 (4x+1)+3 (2x+1)=-x+3

-8x=-64

2/3x+9=5/3x+4

-6x+7-8x=5x+3-5

3/4x+1/2=1/2x+3/2

7 (4x+2)-3 (9x-10)=4

Por favor si me ayudan gracias

Answer 1

Respuesta:

1.

3x - 27 - 6x + 14 = -5

3x - 6x = -5 -14 +27

-3x = 8

3x = -8

x =-8/3

2.

20x + 5 + 6x + 3 = -x + 3

26x + x = 3 - 5 - 3

27x = -5

x = -5/27

3.

-8x = -64

x = 64/8

x = 8

4.

2/3x - 5/3x = 4 - 9

-3/3x = -5

x = 5

5.

-6x -8x -5x = 3 -5 -7

-19x = -9

x = 9/19

6.

3/4x - 1/2x = 3/2 -1/2

1/4x = 2/2

1/4x = 1

x = 1×4

x = 4

7.

28x + 14 -27x +30 = 4

28x - 27x = 4 -30 -14

x = -40
